Septic tank
A septic tank is an underground system used to treat household wastewater. It collects sewage from your home, allowing solids to settle and liquids to decompose naturally through bacterial activity. The clarified liquid then flows out to a drain field for further filtration and absorption into the soil. Septic tanks are common in areas without centralized sewer systems and require regular maintenance to prevent backups, odors, and environmental contamination. They are an effective and eco-friendly way to manage household waste when properly designed, installed, and maintained.
